QtCreator 2.3.x segfaults when loading existing project from welcome screen

Upstream report:

Correct for locally built binaries of QtCreator.
Official binary version 2.3.0 not affected.

Attached detailed GDB trace.

This bug was fixed in the package qt4-x11 - 4:4.8.0-1ubuntu4

---------------
qt4-x11 (4:4.8.0-1ubuntu4) precise; urgency=low

  * Drop kubuntu_92_qml_memory_leak.diff, it causes crashes and has been
    rejected by upstream. (LP: #864475)
  * Update symbols files.
